clan- ELEASE RIGGING.

Specification of Letters l'atent.

- Patented Sept. 5, 1911.

Application filed September-28, 1909. Serial No. 520,050.

the following is a specification.

tion of an end S! 0,

In the drawing i Figure 1 is an end e1evaof a car with my rigging in position on the end sill; Fig. 2 is a top plan view of the same. Fig. 3 1s a sectional view on the line 3--3, Fi 1'.

l'represents theend si 1 of any approved pattern, 2the coupler andB the lockin pin .means of the bolts 5. This casting is pro- 4 is a casting secured to the end 5111' by vided with a slot 6 having flaring ends, whereby the slot iswider at the en s than in the middle, the object of which will be hereinafter pointed out.

. 7 is a ca'stingsecured to the end sill having depending lugs 8 between which is ivoted a bell crank hand-operated lever 9 epending below-the end'sill as shown. The shorter arm of the-lever 9 is perforated and one end jof a link 10 is secured in this perforation in such manner that it has a free movement.

' 11 is the pin operating lever, the outer end of which is provided with an opening 12 in which the upper end of the link 10 is se-' cured in such manner as ,to have a free movement. The inner 'end of the lever 11 is reduced in diameter for some distance to adapt it to slidefreely in the eye of the locking pin 3 to provide 'for the sidewise movement of the idraw bar, thejextreme inner end of the pin? lever being formed into a hook 13 to prevent: its becoming accidentally disengaged from the pin.

The lever 11 is "passed through the slot 6 in the casting 4 and is free to slide therein, thus. said lever may be termed. a floating lever. This lever by reason of its sliding engagement in the slot 6 of the casting 4, and by reason of its link connect-ion with the hand lever 9 is free to slide endwise'to accommodate the sidewise movement of the draw bar and b reason of the flaring ends of the slot 6, it is free to accommodate itself to the backward and forward movement of the draw bar. The contracted portion of the slot 6 prevents the lever from becoming, twisted in lifting; therefore, the lever is always free to move. The upper and lower faces of the slot 6 are rounded as shown in dotted lines in Fig. 1., There is practically no weight of the pin lever 11 on the castin 4, except when operatin because it is'hel in suspension between t e locking pin and link 10 due to. the weight of the lever arm 9. The endwise movement'ffof the pin lever 11 does not afiect the normal position of the hand lever.

Having thus described my invention, what I claim as new therein and desire to seen by Letters Patent is A release rigging comprising a bell crank lever, a floating locking pin lever, a. link forming a connection between the bell crank lever and the outer end of the locking pin lever, and a combined. guide and fulcrum for said locking pin lever on which the lever is free to slide. 3

In testimon whereof I afiix my signature in presence 0 two witnesses.
